Connect the Frame Ground Wire
Connect a frame ground wire to the I/O module's Frame Ground terminal. Connect
the other end of the frame ground wire to frame ground.
CAUTION: The shield ground connections of the RS-232 port, LAN port, PoE
port, I/O port and Frame Ground terminal are internally connected. The
system grounding is at a zero ground potential. This zero-ground potential
extends through the cable and to peripheral equipment, such as a vision
system or PLC. To ensure safe operating conditions, check ground
connections to ensure that they meet a zero ground potential.
Connect an RJ-45 LAN Cable
To connect the vision system to an Ethernet network, plug a LAN cable (RJ-45
connector) into the I/O module's LAN port and connect the other end of the cable to a
switch/router or PC, as applicable.
